Safety switch

A safety switch is used in electrical devices for interrupting the power connection as overloading so as to protect the device to be in safety condition. A safety switch is also used in a locking mechanism that locks the actuator in engagement with the safety switch to provide an extra level of safety which positively prevents opening of the enclosure except in predetermined controlled conditions, for example actuation of a control which turns off machinery within the enclosure. In a factory which accommodates an industrial machine, or in a danger zone around an industrial machine itself, it is required to install a system for locking the drive of the machine. The locking system operates when the door at the doorway is not closed completely, in order to prevent accidents in which an operator may get caught in the machine and injured. A safety switch may be installed within an electronic device for preventing its housing or the internal electronic elements installed therein from being opened or touched by an unauthorized third party as well as issuing a warning alarm by the electronic device if such unauthorized action is occurred.
